BUILT-IN DISPLAY
The second generation built-in display of the Torc is easier to use and more
intuitive than our previous module. It provides useful information, such as
current speed, gear, transmission temperature, and TCC lock status, along
with any fault messages. Using the menus, you’ll be able to access many of
the same options found in Shiftware.
BASIC OPERATION
While the home screen is shown, you can turn the function knob in either
direction to bring up the main menu. The highlighted phrase in the center of
the screen is your
selection. When you’ve found the menu item you wish to
access, push the knob down to click it. Sub-menus work the same as the
main menu. Each sub-menu has an EXIT option which will return you to the
previous menu or the home screen.
HOME SCREEN
Shows real-time transmission information such as speed, current
commanded gear, transmission temperature, TCC lock, PRNDL position,
and any active faults. When low range is engaged, “LO” will be shown beside
speed. “KEY OFF” will show in the PRNDL location if ignition is off and the
controller is being powered by USB. “Error” will show in the PRNDL location
if there is a PRNDL sensor error. When in park or neutral, P/N will be
displayed because 4L60E/4L80E transmissions don’t provide a way for the
controller to see which is engaged. Fault messages will be shown in the
center of the display and will cycle through them if there are multiple errors.
While no errors are present, the home screen will automatically switch to
enlarged mode for easier visibility.
Because the Pressure Switch Manifold (PSM) that is used for range
indication in 4L60E/4L80E transmissions does not distinguish between park
and neutral, the PRNDL display will normally show the position strip as
“RNOD21” with the current range highlighted. When in park or neutral,
“Neu/Pk” will be displayed instead. Since the PSM requires hydraulic
pressure to function, the PRNDL display will not be valid while the engine
isn’t running. Due to this constraint, a “2” will be displayed instead of
“Neu/Pk” on 4L80E transmissions.
